I am a little surprised to hear how many people don't patch tubes. Makes me wonder how I can find the locals with that view. Enough of them and I'd never have to buy another tube.

By the way, OP, regarding your list:

You probably don't need wrenches (plural) for your back wheel, just one that fits.

I carry tire levers too. Some tires you don't need them, others you do, some times you flat when the weather is nice, other times it's freezing and your fingers appreciate the tire levers doing the work.

I also started carrying those thin, disposable gloves so that I don't get grease/grime/oil all over myself from handling the chain.

I also carry a patch kit, though often it turns out impractical to use as it is not always possible to find the leak.
